This invention relates to shoe heels and methods of assembling and attaching thev characteristics'desired in a heel base, and arubber top lift, without detriment to the qualit-y of the finished shoe in which the heel is embodied. l/Vith ythis object in view the invention comprises a .method of assembling and temporarily securing together, with a minimum of labor, an unattached heel base and a. rubber heel, which consists in inserting one or more ,fastenings in the outer face of the base,leavingy theend or ends of said fastening or fastenings projecting,plac ing the rubber heel upon the projecting end or ends in register with the base, and pressing the rubber heel upon the fastening means, which enter the rubber readily and secure theelements of the heel together temporarily suiicientlyto withstand the ordinary handling to which the heelis subject-ed prior to its attachment to a shoe. v rllhe fastenings used may be of any suitable character and may be inserted in the base section in` any desired manner. It has been found convenient and practicalto use for thispurpose a machine of the type disclosed in United States Letters Patent No. 910,147. granted J an. 19, v1909, which is known to the trade as the wire grip tacker. This machine cuts off and drives a headless metallic fastening made from a continuous wire having a corrugated or roughened surface. The machine is very rapid in its operation and makes it possibleto drive a plurality of fastenings, for example, three, asV herein shown, very quickly. No cement is required and'under some conditions it may be suflicient to ,use a single fastening, but under other conditions it will be found preferable to use a plurality of fastenings and, when this is done, the base and the rubber heel are not only kept in assembled relation buty are preventedV from rotative movement relative to each other,'which is an aid in locating the heel easily and quickly in the heel attaching machine. v

rihescope of the invention further comprises a method of assembling and attaching rubber heels and leathcror composition bases which comprises combining and assembling a rubberheel and an unattached'base in their proper positions relative to each other by attaching'means forced into their contacting surfaces andthen nailing both the rubber heel and the base simultaneously to a shoe. YWhen this procedure is' employed it is only necessary todrive a single gang of heel attaching nails, the VassemblingV and attachmfentof vthe heel areeffected with the least possiblenumber of easy operations and,

consequently, at aminimum labor.l cost.

ln'another aspect of the invention animproved unattached heel is provided consisting lof a base'section and a rubber top lift secured ,together by fastenings forced into their-,contacting faces. No cement/is required to maintainthe base and top lift in assembled relation and, inasmuch as the fastenings penetrate only thel contacting faces of the base and top lift, thereis no defacement of any of the exposed surfaces of the theel, as Vis the case `when assembling nailsor other fastenings are driven through either of the exposed faces of an assembled hee1.f

,it should Vbe understood that the term rubber, as used in thisspecilication andthe appended claims, is intendedto denoteanyv y suitable elastic orf-resilient material or composition, such as those commonly lused'in the manufacture of cushion heels. y l

One specific mode of practising the method of thepresent invention and onel example `of the invention as embodiedr in a heelwill now be described in connection `with the accompanying drawings, in which- Fig. l is a perspective yView of a with fastenings inserted in its outer face and projecting therefrom; Y

Fig. 2 shows a machine stapled for inserting the fastenings;

Fig.V 3 shows a rubber heel registered with the base and-forced upon the projecting ends of the fastenings; n

Fig. l shows the assembled heel located heel baseV upon a shoe in a. heeling machine, ready for the heel attaching operation; and

Fig. shows the heel attached to a shoe.

Referring now to the drawings, indicates a leather, orcomposition heel base o-f any usual or desired form. At suitable positions three fastenings 12 are forced or driven into theV outer face of the base 10. It

isnotnecessary Athat the locationof theY fastenings bef-determinedwit-h great eXactness but they should be so placed as not to .interfere withvvthewashers 14 in the rubber top lift lwhen the latter is. registered with the base section, nor with .the heel attaching nails 18 which are to be Vdriven through the said:,washer-s. -Vkv f i In Fig. 2,20 indicates a fasteningiinserting.. machiney of the type above` referred to,

which, as before stated,vis V.well known to the v trade as the, ,wire grip4 tacker. yThis machine cuts off .\from,a;cont1nuou's wire 22 aheadless Y metallic fastening. havinga corrugated or reughened surface and forcesor drives it into they workfheld upon a work ysupport 24. This machine is very .rapid inits operation and, in-Y asmuch. as@` exactnefssin the location of the fasteningjs- 12,v with .respect` tothe heell base seetion10isnotrequired, thethree fastenings shown canbeinserted very quickly.l A single operator, therefor eI with.k a: machine of this kind, can-'prepare a very llarge number of heel bases inaeday. Afterz a 'heel base is prepared., asshown. in- Fig. 1, a-rubber heel or topliftln isiplacedy kupon. the projecting ends 401E-.the fastenings 1,2, in register-'with the base,

and-.ufhpriessed or.A forced upon' the fastening means, ,which enter.. the4 rubber readily and secure f ther elements of theheel togethertemporarily,sufficiently to withstand the ordinaryhadlingto whichthe heel is Vsubjected prior 4to .its yattachment .toa shoe.

` The assembled heel,as illustrated in Fig. 3, is handled as .aunit and mayl beV attached, to a shoe .with azsingle gang 'of'. attachingjnails s driven at,a.single operation. In Fig.' 4, 26

indicates va well known commercial type of heel attaching machine in which a shoe 28 issupported vupon a jack and the assembled heelQisheld in a .suitable holder. The shoe andthe composite heel are registered propf erly with eachother, pressed together, and Vthe attachingnails 18,driven byy a single vwhich:isiplaced in contact with the nates the expensive cement and the waste of time required for the drying thereof, and the time required for the insertion of the fastenings 12 is materially less than is required even for the coating ofthe two parts of theiheel with cement.

lherever, in the foregoing specification! and the appended claims, reference'is made to the -outer face of aheel base it should be understood that the face of the base towhch therubber heel is tobe applied is meant:V This is inaccordance with common usage in the art and this language, wherever it occurs, should be construed accordingly. Likewise it should be understood .that the inner face of the ri'ibber heel or top lift is the attaching face,

of the base.

lHaving described they invention, what is claimed as new anc desiredtobe Vsecured by l YLetters Patent is: A

1. The method` of assembling and temporarily .securing together'unattached heel bases" and rubber heels which consists in inserting `a fastening. from and into-.the outer face of an Outer-face unattached heel base, leaving the end of said fastening projecting from said face, placing :rubber heelin register with the base, andil pressinigtlie `rubber .heel upon the projecting eiidof the fastening to secure ythe rubber heel and base together temporarily?sutlicientlyto j L withstand ordinary handling.

2. The methodl of assembling andftempo, y

rarily securing together unattachedheelbases.,

and rubber heels which consists in inse'rtingfa plurality" of spaced `apart fastenings `from andinto'theouter face of anunattachedheel base,fleaving` theendsofsaid fastenings projecting, from saidrface, registering a rubber.V

heel with said base, and forcing .the rubber heel uponftheprojecting ends of the fastenloe ings to secure the rubber heel and the base 'tol-f j' gether@ temporarily. sufficiently to prevent relative angular displacement or separation ofthe rubber heel and base in ordinaryV handling.

3. The method of attaching rubber and'l leather heels to shoes which consistsin combining and assembling a rubber top lift `and a'leath'er or composition base in their proper position relative to each other by attaching means forced from and into the onterface of' the base and the inner face of the rubber top mentsv to av shoe. l

4: The method of attaching rubber and leather Vheels to shoes, without the use ofy cement, which' consists in securing-the rubber: heelf'to .the leather base by fasteningsforced K fromy andinto'the outer face of the-,base and' the inner face of the-rubber` heel, and there--` lll? lift, and thereafter' rmlysecuring both ele- ,Y

after nailing bothftherubber heeland the base simultaneously to ashoe.

5; The method of assembling and'iattuachingv i' heel bases .and rubber heels` which consists in-` inserting a fastening from and into the outer face of a heel base, leaving the end of said fastening projecting from said face, assembling a rubber heel in register With the base, pressing the rubber heel upon the projecting end of the fastening to secure the rubber heel and base together temporarily, and thereafter'V attaching the assembled rubber heel and base to a shoe by nails driven through both the rubber heel and the base.

6. An unattached, cementless heel for boots or shoes comprising a leather or composition base and a rubber top lift temporarily secured together by driven fastenings Which penetrate only the contacting faces of the base and the top lift. l Y

7. An unattaehed, cementless heel for boots or shoes comprising a leather or composition base and a rubber top lift temporarilysecured together by headless, corrugatedfastenings which penetrate only the contacting faces of the base and the top lift.

In testimony whereof I have signed my name to this specification.
